The PCA2 is a commercial grade, handheld combustion and emissions analyzer for on-demand or semi-continuous sampling of light industrial, institutional, commercial and residential furnaces, boilers and appliances. The PCA2 is the perfect tool for service technicians and boiler contractors who need to ensure safe operating conditions, determine combustion efficiency, or perform emissions testing in combustion applications.
The PCA2 directly measures and displays flue gas Oxygen (O2), Carbon Monoxide (CO), Stack Temperature, Draft, Differential Pressure, and Combustion Air Temperature. Simultaneously, the PCA2 calculates and displays combustion efficiency (EFF), Excess Air (EA), Carbon Dioxide (CO2), and Oxygen reference values. The PCA2 performs combustion calculations for ten fuels including, Natural Gas, Oil #2, Oil #4, Oil #6, Propane, Coal, Wood, Kerosene, Bagasse and Digester Gas. The large backlit graphic display shows eight different measurements and calculated values simultaneously, and also has zoom capabilities.
